Application February 16, 1955 Serial No. 488,497

8 Claims. c1. 189 69) invention relates to a pivotally mounted and laterally shiftable window and more particularly to a window mounted in the grid of a facade of a building and in which the sashes are so pivoted that they may be swung through an angle of three hundred and sixty degrees.

One of the principal objects of the invention is to provide a window in which the sashes may be swung inside out, so that both side faces of the window may be readily cleaned from inside the building and still maintain the window wind and watertight when in its closed position.

Another object of the invention is to provide a window in which the pivotal axis of the sashes may be shifted with respect to the sides of the opening in the grid of the facade in which the sashes are mounted.

A still further object of the invention is to provide a window which may be repaired and cleaned on both side faces without the use of scaffolding. I

A further object is to provide a window with a slidable sealing means at both its top and its bottom to seal the joints betwen the top and the bottom edges of the window and the grid. r v

Another object is to eliminate the necessity of a window frame and to close and/or seal the window against the grid of the facade of the building.

Still another object of this invention is to provide a window provided with two pivoted sashes so; mounted that they may be opened by first shifting their pivots laterally outwardly from the window until the edges of the sashes clear the jamb portions on the grid, after which they may be independently rotated on their pivots to the desired positions.

Other objects will appear hereinafter specification.

Referring to the drawings:

Figure 1 is a horizontal section through my improved window construction taken on a plane just above the top edge of the window;

Figure 2 is a view similar to Figure 1, but showing the window sashes shifted laterally into a position to clear the jamb portions of the grid and before the sashes are rotated on their pivots;

Figure 3 is a view similar to Figure 2 but showing the sashes each swung approximately ninety degrees to an open position; v I

Figure 4 is a vertical section through parts of the throughout the facade and building structure adjacent a window and showing the window in open position; v v I Figure 5 is a vertical section similar to Figure 4 :but on an enlarged scale and with the window closed;

Figure 6 is a horizontal section throughparts of sashes of two different adjacent windows, in their closed positions, and a part of the grid structure, which, serves as jamb portions for the adjacent sides of thelsashes of the windows; and s Figure 7 is a view similar to Figure 6 but showingjthe adjacent sides of the two sashesofawindow and their relation to the grid structure which serves as aeommon jamb member therefor. This figure also shows portions of the lower sash-actuating links and the pivot which connects them to the window sill.

Referring to the drawings, A represents openings in the grid of a facade B for a building in which a window C is mounted. This window comprises two sashes 1 and 2 which are connected to the head D and the sill E of the window and to each other by pairs of pivotally connected links. The link arrangement at the sill and at the head are the same and each comprises a pair of links 3 and 4 of the same length pivotally connected together at one end and to the head at 5. The other end of the link 3 is pivotally connected to the top of the sash 1 midway between its'sides at 6, while the link 4 is connected in like manner to the sash 2 at 7. The links 8 and 9 of the second pair are of the same length and pivotally connected at one end to a link of the first pair and to a sash, and at their opposite ends to each other at 10, the link 8 extending from the pivot 6 to. the pivot 10 and the link 9 from the pivot 10 to the pivot 7.

I As shown in Figures 1, 2, 3 and 6, the grids 11, at the sides of the window, are of substantially I-shape in cross section, forming vertically extending slots 12 into which the adjacent sides of the sashes project when in their closed positions. These grids also serve as jamb portions to receive portions of the side faces of the sash when the window is closed. These jamb portions carry gaskets 13 to seal the joint between the sash and the grid when the window is closed. Each window has a vertically disposed jamb portion 14 in the middle of the opening against which the adjacent sides of the sashes 1 abut.

when in closed position. This jamb portion is also pro vided with gaskets 13 to seal against the sashes.

'As shown in Figure '5, spandrels 15 may be mounted in the grid openingsabove andbelow thewindow, if desired. Gaskets 13 or other suitable sealing means may be used to seal the joints between these spandrels and the grid structure. i

In order to seal the top and the bottom of the window, an upper and a lower retractible weather bar is provided. Each of these bars is slidably mounted in the grid structure. The upper bar 16 has a horizontally extending flange 17 which may serve as a handle to reciprocate the bar. This bar also has a slot 18 in its lower portion which straddles a flange 19 on the window sash. The bar 16 extends from one side of the window to the other and seals against a gasket 13 or other suitable sealing means. When the bar 16 is raised above the flange 19, the sash is free to rotate on its axis. The'bottom weather bar 20 is the same in structure as the bar 16 but is inverted.

The term facade used in this application is intended to cover' any frame, panel, building face unit,'or other structure that may be used to rnount a window and/or panel in the side of a building.

While the improved window disclosed herein is shown and described as having its sashes mounted on vertical pivots, it is apparent that they could also be mounted on horizontally disposed pivots. 1

- While the weather bars are'shown as being carried by the grid of the-facade, it is to be understood that they may be carried by the sashes, if desired.

The operation of the window as illustrated in the several figures of the drawing will now be described.

Figure 1 shows the window in its fully closed position with the upper and thelower pairs of links disposed in the same plane as the sashes. To open the window, the weather bars are first moved to their inoperative positions, the upper bar being raised and the lower one lowered. The sashes are then moved to the position of Figure 2 which movement frees them from the slots 12in the grids 11 and ma position to berotated on their pivots 6 and 7. As will be seen from Figure 3, the sashes may be rotated on their pivots through three hundred and sixty degrees so that both faces may be cleaned or repaired from inside the building. The window may be closed by rotating each of the sashes into a position in the plane of the link 8 or 9 to which it is pivoted. The links are then folded into the same plane which positions the sashes in their closed positions against the gaskets 13 on the jamb por tions 11 and 14. The bars 16 and 20 may now be moved to their sealing positions.

While Figure 3 shows one openposition of the sashes, it is apparent that they could assume many other positions, for example, the sashes could be moved to positions closely adjacent the middle jamb portion and in spaced parallel relation.

The above description and drawings disclose a single embodiment of the invention, and specific language has been employed in describing the several figures. It will, nevertheless, be understood that no limitations of the scope of the invention are thereby contemplated, and that various alterations and modifications may be made such as would occur to one skilled in the art to which the invention relates.
